Hi, new to this forum so please give me some slack if I'm asking the wrong type of question or it has been covered previously.

Anyway. I currently have a 2011 Sworks Stumpjumper with Sram XX group set and brakes. The bike is less than six months old and I've had brake trouble since new. After a drawn out process of trying to rectify them (new lever assemblies etc) my LBS has had authorisation to change them to something else FOC under warranty.

So, I'm looking for some suggestions on what to go for as I want to be sure I get the best for my needs. I ride mainly on the North Downs in the UK and occasionally North Wales and trail centres. I'm not heavy and I'm very light on my equipment. The LBS seems to be suggesting that XTR would be a good choice, but will supply what ever I want. The downside is that I won't be able to run the matchmaker clamps and will now have to have two clamps on each side of the bar. I'd like them to be as light as possible but also reliable.

Any thoughts?

Hope Race X2, less brakepower compared to XTR (have Trailversion myself), but because you're light and in combination with 180mm discs you'd still have plenty brakepower and most important: modulation.I weigh 80kg and the XTR is awesome in terms of power and modulation, made me even more confident on gnarly descents.However, I had 2 muddy rides and pistons got stuck, or didn't move enough.Taking out the pads, cleaning the pistons edges solved the probs, but never heard similar reviews about the Hopes from buddies around, those are seemingly more install and forget (not the buddies, the brakes ).They only claim to want more braking power, but again, since you're a light rider...I would have chosen them too, but because of my weight and above comments went for the XTR.Formula is also super, but I hear lots of comments about pad rubbing on the discs in whet conditions.

Either Shimano or the Magura MTs....Avid's are having so many problems that some manufacturers are switching to other brands as OEM suppliers. Very soon you will also see Maguras as OEM on some 2013 bikes.

I have used their Hope Mono Mini. Then on another bike I got their Mono Mini Pros. Then when the X2 race came out I built another bike with X2 race.

All are superb. Easy to maintain. Excellent modulation. Their customer service is amazing. The bleed process is easy (no syringes or stupid fancy bottles). They are install and forget (but check your pad thickness every year).

I have also test ridden the X2 Race EVO, they are even better with a nicer brake lever that makes the brakes seem more powerful as the lever is less effort to activate.

I have also test ridden the new M985 race XTR brakes. They too are great. I don't own them, so I can't speak to their easy of maintenance or durability. They have decent feel with lots of power. The plus side with XTR is that they are popular and any bike shop should be able to service or find you parts immediately. Also Shimano sponsors many of the local mountain bike races, so that if you have a problem, there is a neutral support shimano tent.

For me, I like Hope. If you don't go with hope, you should go with the XTR.

I have just asked the same question a couple of weeks ago. The advice I got in this thread- viewtopic.php?f=1&t=102673 - was great and really helpful.

In the end I went for XTR and I couldn't be happier. No rub, no complicated adjustment, great braking. Coming from V-brakes and having been utterly skeptical concerning disc brakes I have to admit I would never go back. XTRs work absolutely superb for me.

Don't go XTR. They are very finicky and need to be bled quite a bit. I have found that the XTs are choice though. They are much more consistent from the factory and they are easy to forget that you even have. Low maintenance is king.

I think that is the exact problem Colin. You shouldn't have to bleed brakes first time out of the box. They should just be working when they arrive from the factory. I have seen XTR sets brand new out of the box that had an entire lever reservoir full of air.
